[PATCH v4 0/7] posix timers fixlet

[kosaki . motohiro]

From: KOSAKI Motohiro <kosaki.motohiro@xxxxxxxxxxxxxx>

Glibc's posix timer testcase found a lot of bugs in posix timer code.
This series, hopefully, fixes all of them. All patches are independent 
each other logically.

Changes from v3
 - task_sched_runtime() micro optimization add to care tsk->on_cpu.
   suggested Paul Turner.
 - fixed several typo in changelogs.


KOSAKI Motohiro (7):
  posix-cpu-timers: don't account cpu timer after stopped thread
    runtime accounting
  posix-cpu-timers: fix acounting delta_exec twice
  posix-cpu-timers: fix wrong timer initialization
  posix-cpu-timers: timer functions should use timer time instead of
    clock time
  posix-cpu-timers: check_thread_timers() uses task_sched_runtime()
  sched: task_sched_runtime introduce micro optimization
  posix-cpu-timers: cleanup cpu_{clock,timer}_sample{,_group}
